Personal Information. Don’t give out personal information without your parents’ permission. This means you should not share your last name, home address, school name, or telephone number. Remember, just because someone asks for information about you does not mean you have to tell them anything about yourself!.
Screen Name. When creating your screen name, do not include personal information like your last name or date of birth.
Passwords. Don’t share your password with anyone but your parents. When you use a public computer make sure you log out of the accounts you’ve accessed before leaving the terminal.
Photos. Don’t post photos or videos online without getting your parents’ permission.
Online Friends. Don’t agree to meet an online friend unless you have your parents’ permission. Unfortunately, sometimes people pretend to be people they aren't. Remember that not everything you read online is true.
Never but personal stuff about you online because you never know who's looking at it.
